My 2004 Endeavor XLS AWD is finally ready for its 60K maintenance, and the list is quite extensive according to the Mitsubishi service schedule. The biggest items are the timing belt (which I'm thinking is fairly important to follow the recommendations on), spark plugs and ignition cables (which I'm not so sure about). The dealer is also recommending items not on the manufacturers schedule, such as transmission flush, fuel system cleaning (I've always run 93 octane) and engine oil flush (?), all of which I'm inclined to skip and just stick with the manufacturer recommendations.

I'd really appreciate input and recommendations from the Mitsubishi experts out there as the preliminary quote I got from the dealer is already almost $1,700, and I'm not even sure if that includes the ignition cables and all of the other items on the schedule. Also, I've noticed that changing the transmission fluid appears nowhere on Mitsubishi's maintenance schedule for the first 120K miles. Any thoughts on this would be welcome. Thanks.
